The object of the invention is to improve the rconstruct-ion ont s .device of this class.

In the accompanying drawings, Figure l is a side elevation ofen. implement embodying the features of my invention, Fig. 2 is e sectional View taken in the plane of' dotted line 2 2 of Fig. l. Fig. is e' fragmentiil side 4elevation showing; `the jaws ci the implement es closed together. Fig. Il is r:i longitudinal sectional View through the jaws in tlie separated or open position. Fig. 5 1s a similar View showing the-jews closed. Figs. (i and 7 are sections on lines o 6 and 7, respectively, ci Fig. Il. Figs. 8 rind 9 are perspective views of two punches comprised in the mechanism. 1), il sind 12 illus trate the steps in the operation ci' fastening two sheets together..4

The implement herein shown is adapted in contact with onel smother, by cutting e tongue-shaped portion ont of ell the sheets, one end of the tongueremsining attached. .to the sheets, and bending loaclr said tongue and passing it through e slit in the sheets.

The implement comprises two similar eloir ated'ja'ws which will be teimedtlie upper )aw 1 and the lower jaw 2. Each jewrconsists preferably oft' ya sheet-metel stamping.

The implement is held in theliendand op- @rated by means of two handles 3 which ere pivotally connected hy a rivet or pin e. The

Y inner end of each handle is extended beyond the pivot lin the `two portions 5. In order that the yjaws 1 and. l may be maintained in parallelism when opened and closed oy the handles, the forward portions oi said jaws are pivoted between the handle ortions 5 upon pivots 6, end the resi' portions of said jaws ere pivotally and slidohly connected with the hendlesi by pins 7 fixed iii` the handles and passing through-slots 8 in the jaws. f The pivot 6 and the pin 7 for erich jew ere equally distant from the pivot e, whereby parallelism of 'the jaws is preserved during;r the movements of the latter. For opening the Jaws I provide coiled tensionsprings 9 each attechedat one end to the outer end of one ofthe handles, upon the inner side thereof, and connected at its other end to they inner end of'one of the jaws. When the jawsare closedrtogether, the springs 9 are iiexed or extended, whereupon whenl the pressure upon the handles is relaxed, the springs contract, and open the jaws.

it.' die plate 10 is iixed upon the upper I l side oi the lower jaw 2 bymeansof a screw l1 extending upwardly through the jaw and the die plate, a nut 12 being turned on said screw sind hearing upon said plete. vIn, the plate 1G is formed a die openin 13. The

lower well ol." the jaw 2 is prelerably cut away, as at 14, below the opening 13.

A. stripper plate 15 is located above the die plate l0 end is cured in place by a screr7l 16 passing through the rear ends of the plates 3.0 and 15 and the jaw 2, a nut 17 being turned on the upper end ofthe screw. The stripper plate d5 has an opening therein through which the nut 12 extends said nut having a flange 18 thereon to limit the upwerd movemeiiisof the stripper plate. Said plete tends to lie in contact with the die- Vplete 10," out is moved away from the die plete l0, so as to provide a space to. receive" the sheets to loe fastenedtogethei, bly shoulders 5 on the `handle portions 5 un erl ing the side portions 15et of the stripper yp ate. See Figs. 1 end`2. Openings -19 and 2O are formed in the stripper plate fr the passage 'of the cutters to be next described. The upper jaw yconsists of two side wells and e telg` well, while the lower jew consists of. two ide walls and e. lower or bottom we, l
